Hi, We bought the ebay one last year to shift the boat around the side of the house. Unfortunately it also needs to push uphill and a grass surface. To make it worse, the tyres on the trailer aren't the widest they could be. Even with the lug tyres we have, the wheels will start to spin and you go nowhere. Latest project was a winch mounted on the front so when it starts to slip you engage the winch and it walks it into the garage. We made a Y harness that goes between the two rear uprights for the winch to attach to. If you have flat ground or perhaps concrete, pretty sure it would do the job. Boat on its trailer is around 1300kg. I'll post a couple of pics later.
